ELECTRODE.

Application filed June 6,-

This invention relates to improvements in vacuum electrodes which are filled with a precious gas and used for the therapeutical treatment of diseases. They are intended I to replace the electrodes used heretofore which produce a bluish White or reddish blue colored rays.

It is the principal purpose of this invention to produce an electrode of this character which can be used with high frequency current apparatus to produce yellowish light rays.

Another object of the invention is the provision of such an electrode which is filled with helium gas and the rays of which are yellowish in the spectrum and have a healing capacity for certain kinds of diseases.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds and will then be specifically pointed out in the appended claims.

In the accompanying drawing, forming a material part of this disclosure:

The single figure illustrates in sectional side elevation the preferred form of an electrode constructed according to the present invention.

The vacuum 1.0 of any suitable shape or form, carries a cathode 11 held within the tube by means of a holder 12 and connected by means of a wire 13 or the like with a metal sleeve 14 upon the restricted front end of the electrode, adapted to be connected with a high frequency current apparatus.

The electrode as illustrated in its preferred form is principally intended for the 1923. Serial No. 643,748.

treatment of skin diseases, it may however, as stated above, have any suitable form allowing a treatment of the various cavities and other parts of the human body.

It is therefore understood that I do not wish to limit myself to the specific form illustrated as an example, but that such changes may be made which fall within the scope of my invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: 4

1. As an article of manufacture, an electrode comprising a tube containing a gas and having a restricted laterally extending handle portion, a holder within the tube, a cathode within said holder, a metal sleeve upon the terminal of the laterally extending portion, a wire connecting said sleeve and cathode, and a quartz plate covering an opening formed in one end of the tube, the

tube proper and lateral extension being charged with helium gas. 2. An electrode comprising a tubular body rounded at one end and flaring at the opposite end, an electrode holder extending longitudinally and centrally over the body from the rounded end and a handle member formed as a lateral extension open to and communicating with the body and pro'ecting from one side of the body interme iatethe ends and at a point substantially midlength of the electrode holder.

In testimony whereof I have afiixed my signature.
